UV and you


With the recent wave of summer sun, brings an increase of UV. Come rain or shine, we are always susceptible to the harm of UV rays. In the summer months however, exposure is at its peak! Fight for Sight, an eye research charity found only 1 in 2 of us are wearing UV blocking sunglasses. 

Here are 5 tips to reduce UV damage:

Darker lenses don't necessarily mean better protection! Sunglasses aren't equal in their ability to block UV. So a tint can be purely cosmetic with or without blocking UV well.
Tip: Look for CE marks to ensure your lenses meet the European standard for UV protection. 

It's a common misconception that we don't need protection on cloudy days. This may be true for wearing a tint,as it may not be as bright. UV however can penetrate through the clouds, so is still present, even when the sun isn't shining.
Tip: Day to day spectacle lenses can now be glazed to completely block out the sun's UV, therefore preventing long term damage. So now, clear lenses can give full coverage, all year long.

Have blue eyes? It's true that people with blue or lighter coloured eyes are more at risk of UV damage. Which in turn increases the risk of AMD. This is because lighter coloured eyes contain less melanin, a naturally occurring protective pigment.
Tip: Become familiar with the risk factors that contribute to AMD (Read more about AMD here). 

Sand and water are highly reflective, so they increase the UV levels in the surrounding area. If you're visiting the beach or planning a holiday, be sure to have protective sunglasses ready. 
Tip: Polarised lenses are extremely effective at blocking out glare, giving clear, undisturbed vision even on the sunniest of days. 

Our most vulnerable time, is up to the age of 5. After this our lens becomes more adapted to blocking out UV; so we better protect our retina (the camera film like layer, at the back of the eye). Damage done at this age can contribute to the development of cataracts later on in life.
Tip: Making sure your children have the appropriate sun protection, will help to reduce the cumulative effects of UV damage early on. 

If you are frequently exposed to UV, whether walking the dog or vacationing in warmer climates, you should protect your eyes. Be sure your sunglasses provide good vision, a high level of protection and enjoy the summer!
